Tooth whitening is a cosmetic dental procedure aimed at lightening the color of teeth. It can be achieved through various methods, including over-the-counter products, professional treatments, and at-home kits. The process typically involves the use of bleaching agents, such as hydrogen peroxide or carbamide peroxide, which help remove stains and discoloration. Many people choose tooth whitening to enhance their smile and boost their confidence. While it is generally safe, it is important to consult with a dentist before starting any whitening treatment to ensure it is appropriate for individual dental health and to avoid potential side effects, such as tooth sensitivity.
